For outreach, use a Google Workspace address on a domain you own if you can spend about $100 a year and an afternoon on setup. A free Gmail account works for a first test of a few dozen emails, but you can't control its authentication, and the address looks like personal mail. Whichever you pick, don't send cold email from the inbox you use for everything else.
Most comparisons of the two list storage, video meetings and support. For outreach, four things decide it: how the address looks in an inbox, the sending limits Google publishes, how long setup takes, and what it costs. Here they are in that order.
The two options in plain words
A free Gmail account has an address ending in gmail.com. A Google Workspace account is a paid Google account whose address ends in your own domain, such as lena@hartfinance.example. Both use the Gmail interface and both send through Google's servers. The paid one lets you control the domain, and with it the records that prove mail is really from you.
Side by side on the four things that matter
| Factor | Free Gmail | Google Workspace |
|---|---|---|
| Address | name@gmail.com | name@yourdomain.com |
| Daily sending limit, per Google | 500 emails or 500 recipients in a message trips a restriction | 2,000 messages a day; 500 on a trial account |
| Setup | Minutes | 1 to 3 hours the first time, plus DNS waiting time |
| Cost | $0 | Business Starter listed at $7 per user per month on a one-year commitment, plus the domain |
The limits and price are as published on Google's own help and pricing pages in October 2026. Google runs promotions and changes prices, so check the pages before you buy.
Address credibility: how it looks in an inbox
A buyer deciding whether to open a stranger's email sees the sender name and the address. An address on a real domain lets them check the website behind it, which is what a careful person does. A gmail.com address gives them nothing to check. That matters more in some markets than others. Plenty of plumbers and bakers use Gmail themselves and won't blink. A finance director or an office manager at a larger firm is more likely to read gmail.com as a one-person operation or a mass sender.
There is a second, quieter cost. On free Gmail you can't publish your own authentication records for the address, because you don't own gmail.com. On Workspace you can turn on DKIM for your domain and add SPF and DMARC. Those are the records that let a receiving server confirm the mail is yours. Our setup guide walks through all three. A free account can also "send as" a custom address through Gmail's settings, but the mail is then signed by Gmail, not by your domain, so the identity checks don't line up. It's a workaround, not a setup.
Sending limits, as Google publishes them
Google's help page for personal accounts says that sending to more than 500 recipients in one message, or more than 500 emails in a day, can trigger a restriction, and that you can usually send again in 1 to 24 hours. Workspace's page lists 2,000 messages a day for a standard account, 500 for a trial account, and a cap of 3,000 external recipients a day. Exceed them and sending stops for up to 24 hours.
Those are ceilings, and no cold sender should be near them. A new inbox that jumps to hundreds of emails a day gets flagged long before 500. Plan for 20 to 50 a day per inbox at the start and build from there, as laid out in how many cold emails per day from Gmail. So the 500 versus 2,000 gap shouldn't decide anything. If you do hit the wall, what to do when Gmail says the daily limit is exceeded has the fix order.
Setup effort
Free Gmail takes minutes. Workspace takes longer, and most of that is waiting. You buy a domain from a registrar, sign up for Workspace, prove you own the domain by adding a record in your DNS settings, point your mail records at Google, then turn on DKIM and add SPF and DMARC records. The typing takes one to three hours the first time. DNS changes can take hours, sometimes a day or two, to show up. Do it on a weekday morning, not the night before a campaign.
What it costs for one outreach inbox
Lena is a fractional CFO in Raleigh who sells a $1,500-a-month finance retainer to small companies. Her annual cost for a Workspace outreach address is about $84 for one user at the listed $7 a month, plus roughly the price of a domain, under $25 for a year at most registrars. Call it about $100, or $8 a month. One signed client from outreach would cover that for over a decade. The free option costs $0, and her real cost is a less credible address and no control of the records. The numbers change for a team: ten inboxes at $7 each is $70 a month, which is why many teams start with two or three.
Which to start with
- You are testing the idea with 30 to 100 emails: a brand-new free Gmail account used only for this, not your personal one, is fine. You are measuring replies, not building a brand.
- You have a business, a website and a plan to keep doing outreach: Workspace on a domain you own. Read whether to use your main domain or a separate one first, because that choice protects your regular business mail.
- You already pay for Workspace: add a new user for outreach rather than using your own mailbox.
Moving later is simple, with one catch: reputation doesn't transfer. A new address starts from zero, so plan two weeks of low volume as described in warming up a Gmail account. Tell your existing contacts the new address, set up forwarding from the old one, and update your signature. The mechanics of sending from either are in how to send cold emails from Gmail, and if you're thinking about bulk tools, mail merge in Gmail shows where they stop working.
Rocketship sends from whichever Gmail or Google account you connect, free or Workspace, so you don't have to decide before you start. It finds the buyers, emails them from your own Gmail, follows up, and books the meeting on its own. Plans that get you customers start at $24.99 a month (Launch), and every monthly plan starts with a 7-day free trial, card required. See how the AI workers run outreach.
